ST. PETERSBURG, Fla. -

A homeless man is in jail after throwing pieces of concrete at a St. Petersburg hotel.

Police said David Allen Jensen, 41, told them he was trying to get inside the hotel early Wednesday because zombies were chasing him. They said he broke the glass at the Hilton St. Petersburg Bayfront hotel with a doughnut-sized chunk of concrete used to protect sprinkler heads.

The World Anti-Doping Agency (WADA) said Sunday it was "very alarmed" by reports of widespread doping by track and field athletes in major competitions including the Olympic Games and world championships.
